  • Metronix – smartServo BL 4840-M/D decentralised solutions

To visualise the extreme performance of the smartServo BL 4000-M/D servo drive, we have chosen an example from nature: The ant can move objects that exceed its own body weight by a multiple. Just like the compact BL 4000-M/D, that moves for example a machine tool, a packaging machine or a robot precisely, dynamically and controlled. This is an important component for your current and future projects. 

 
Saving of control cabinet space
  • Usually no control cabinet required for servo drives
  • No cabling between motor and servo drive if the servo drive is installed on the motor
  • Supply with low voltage of 48 V via PELV power supplies or batteries
  • No high voltages at the motor and servo drive
  • USB and Ethernet as parameterization interface
  • Fieldbus on board EtherCAT, PROFINET, optional CANopen
  • Bluetooth interrogates the servo drive status via smartphone or tablet
 
Universal encoder evaluation
  • HIPERFACE®
  • HIPERFACE DSL®
  • EnDat 2.2
  • Resolver
  • Analogue and digital incremental encoders
  • BISS
 
Protection

High protection class for long-lasting operation in rough environments

Thanks to their particularly robust design and excellent manufacturing, the decentralized smartServo drives comply with protection class IP67.

The IP67 protection class protects the servo drives against dust, contact and even submersion. This allows them to be used without a protective housing. They quickly and effectively meet even “large” requirements.

 

Safety

STO – Safe Torque Off

Disconnection of the energy supply to the drive according to EN 61800- 5-2. This safety function ensures that the drive is unable to deliver energy.

SS1 – Safe Stop 1

The drive is braked self-sufficiently to idle within a defined time using a defined slowdown ramp and then the energy supply is switched off safely. SS1, Type C is supported.
